Question

If the requirements of np greater than or equals 5np≥5 and nq greater than or equals 5nq≥5 are both satisfied, estimate the indicated probability by using the normal distribution as an approximation to the binomial distribution; if np less than 5np<5 or nq less than 5nq<5 then state that the normal approximation should not be used. With n=39 births and p=0.512 for a boy, find P(fewer than 16 boys)

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
